yoast_seo_metatags_alter relies on removed code

The title and description editing uses yoast_seo_metatags alter to insert the title and description where needed.

However in applying all the tested patches it was missed that the methods from $seo_manager that it relies on no longer exist.

A temporary workaround is to patch out the yoast_seo_metatags alter. However, a method needs to be found to check if a yoast_seo field exists and get its value.
